Patented J an. 9, 1912.

To all whom it may concern:

Be it known that we, D D MILLER and DAVID E. RowLAND, both citizens of the United States, both residing at Canton, in the county of Stark and State of Ohio, have invented a new and useful rlrip for Hay and other Carriers, of which the following is a specification.

Our invention relates to improvements in carriers designed to be used for conveying hay or other material, the said carriers being suspended from a track or way, and

has special reference to the trip used upon aA cable or rod track or way for operating the clutch mechanism or tripping dogs of the carrier mounted thereon.

The objects of our invention are to generally improve devices of the character mentioned, to provide a trip which will be compact, strong, easily manufactured, positive in operation, and which will permit the carrier to pass over the said trip when located upon the track or way.

A further important object is to so construct the trip that the clutch or dog operating portion thereof may at all times hang vertically beneath the cable or rod constituting the track, any twisting or turning of the cable or rod to vwhich the device is connected not affecting the proper disposition of the said portion of the device.

These objects together with other objects readily apparent to those skilled in the art we attain by the construction illustrated in the accompanying drawing in which- Figure 1 illustrates in side elevation a track or way consisting of a cable with a hay carrier mounted thereon and a trip embodying our invention properly arranged upon the said cable. Fig. 2 is a longitudinal sectional view through the trip taken on the line 2 2 of Fig. 3. Fig. 3 is a transverse sectional view taken on the line 33 of'Fig. 2. Fig. 4f is a perspective view of one of the clamping wedges. v

Throughout the several views similar numerals of 'reference indicate similar parts.

The numeral 1 indicates a cable preferably made of steel, although other suitable material such as hemp may be substituted, or a round rod or other track or way may be used without departing from the spirit of the invention, it being understood that said cable or rod is suspended onlyat the ends to suitable supports.

The numeral 2 indicates the upper frame of a carrier provided with revoluble wheels 3 adapted to run along said cable 1. The lower frame 1 is swiveled to the frame 2 in the manner well known in the art, permitting the said lower frame to be reversed for the purpose of operating the carrier in either direction from the trip.

The numeral 5 indicates one of the dogs or gripping devices which is operated by contact with the trip. L

Further description of the carrier is unnecessary as no part thereof is claimed herein.

It will be understood that in the operation of the carrier on the cable it is desirable to provide a trip which will engage the dog 5 by reason of the movement of the carrier along said cable. It is also desirable to so arrange said trip upon said cable that while a firm fastening is made thereto no part of the said trip will prbject in such manner as to interfere with the travel of the wheels 3 over the same. Heretofore devices have been employed in which set screws or other means have been used, but set screws usually project laterally from the device and if the cable twists to any extent said set screw may be thrown into such position as to interfere with the travel of the carrier along said cable and overthe trip. In the present invention it is to be noted that while the trip is `iirmly clamped to the cable, no lat erally projecting set screw or other device is employed and that although the cable may twist in some instances, the free passage of the carrier is not interfered with.

The trip consists principally of a main sleevej, a swinging block 7, an adjusting sleeve 8, and the clamping wedges 9. The main sleeve 6 is provided with a longitudi-V nally disposed aperture which at the end designated by the numeral 10 is of just sutlicient size to accommodate the cable l the said aperture slightly increasing in size from the said end 10 toward the opposite end, the walls of said aperture being thus convergent toward the end 10. At the end of the sleeve 6 opposite the end 10 are arranged internal screw threads 11 adapted to engage corresponding external screw threads on the adjusting sleeve 8. Said adjusting sleeve is provided with a longitudinal aperture of appropriate size to accommodate the cable 1 and the inner end of said adjusting sleeve is formed with a shoulder 12 adapted for engagement with the thicker end of the wedges 9. rlhe main sleeve 6 at the end 10 is provided externally with an elongated, slightly inclined or conical outer surface carrying the external surface of said sleeve gradually down to the external surface of the cable, thus permitting the wheels 3 to readily ride up said inclined surface without encountering any considerable resistance.

The adjusting sleeve 8 is provided with screw threads for a portion only of its length and the portion of said sleeve which projects outwardly from the sleeve 6 is provided with a similar conical outer surface, over which the wheels 3 may travel as in the case of the oposite end of the sleeve 6. The flat surfaces 13 are ground or otherwise formed upon the conical surfaces of the sleeves 6 and 8 for the purpose of permitting the ready application of an ordinary wrench in turning t-he two sleeves with relation to each other for adjusting the sleeve 8.

Intermediate the ends of the sleeve 6 1s formed a broad, flat, annular depression 14 within which depression is located the band 15 of the swinging block. It should be understood that the swinging block, designated generally by the numeral 7 consists of the said band 15, the integral head 16, the horizontal integral ange 17 and the depending flange 18. The preferable method of arranging the swinging block upon the main sleeve 6 is to cast the said main sleeve with the depression let therein and subsequently to cast the swinging block with the band 15 forming an integral part thereof, extending around the sleeve 6 and located in the said depression, the proper steps being taken when casting the said swinging block so as to provide for the free rotation of the said band 15 about the sleeve 6. It should be noted that the band 15, being attached only to the main sleeve 6 and being kept in place thereon and out of engagement with the adjusting sleeve 8 by reason of the depression 14, any rotation of said band with respect to said sleeves, or any shocks or jarring of the device in operation will have no tendency whatever to unscrew the adjusting sleeve 8 with reference to the sleeve 6, and thus loosen the device on the cable. The weight of the portions 16, 17 and 18 of said block is suflicient to maintain it in its normal pendent position by gravity.

The clamping wedges 9 are substantially of the form illustrated in Fig. 4f and consist of tapering or wedge shaped pieces curved transversely to fit the walls of the interior longitudinal aperture of the main sleeve 6 as well as the cable 1. In applying the trip to the cable the said cable is threaded through the sleeve 6 and adjusting sleeve 8 and the wedges 9 are then introduced into the sleeve 6 with their thinner ends directed toward the end 10 of said sleeve. The adjusting sleeve 8 is then screwed into the sleeve 6 as illustrated in Fig. 2, whereupon the shoulder 12 will engage the thicker ends of the wedges and force said wedges toward the end 10 of the sleeve 6, thereby clamping the cable tightly between them and firmly fastening the sleeves 6 and 8 with reference to said cable. It should be noted that the preferable number of wedges is two, although one wedge or more than two wedges may be used without departing from the spirit of the invention.

When properly adjusted upon the cable the swinging block 7 will assume the position illustrated in Figs. 1 and 2 and the depending flange 18 will then engage the dog 5 of the carrier when the said carrier is moved along the cable to the trip.

It should be especially noted that while the carrier illustrated in Fig. 1 is shown as operating along that portion of the cable to the left of the trip, that the carrier may be reversed and operated on that portion of the cable to the right of said trip, the said trip being of such formation as to permit the wheels 3 to pass over the same without inconvenience or unusual adjustment. Attention should also be called to the fact that while we have shown the swinging block provided with the horizontal ange 17 and depending flange 18, yet it will be understood that any form of head or ianges may be connected to the band 15, reference being had to the particular carrier to be used upon the cable or track andthe necessary form of dog engaging device to be used with such carrier. By reason of -the fact that the swinging block is so connected to the main sleeve that the bearing of said block will be upon a portion of said sleeve, it will be noted that the cable is relieved of the wear which would naturally result if the said block were allowed to swing or pivot upon the cable itself. At the same time the main sleeve, being of one continuous length is less liable to wear the cable, and the fastening means for clamping the device to the cable, engaging a .considerable surface of the same is well adapted to produce a firm fastening while at the same time producing no appreciable wear upon said cable and displacing the strands thereof to a much less degree than a set screw or other common form of fastening means.
